Rollprint Adds to High-Barrier Line
- Published: November 11, 2014
ADDISON, IL | Rollprint Packaging Products announces the addition of a second high-barrier structure to its Exponent film family. Exponent 2 features a combination of company’s ClearFoil and a coextruded, non-crystalline polyester sealant. (Company says the non-crystalline attributes enhance sealing properties.) 
The material targets pharmaceutical and other chemically sensitive applications that require exceptional barrier and clarity. Pre-made or inline pouching, lidding, and flow wrap applications are expected to be the first commercialized package types.
Reportedly, the structure’s reduced number of layers and gauge offer cost-savings and create an improved environmental profile for a wide variety of pharmaceutical products, and high-barrier and clarity properties make it a suitable replacement for glass vials.
Exponent 2 has been engineered to provide a chemically neutral, ultra-high oxygen and water vapor barrier with chemical resistance. Oxygen barrier levels are available as low as 0.0008 cc/100in2-24 hrs and water vapor barrier properties are available down to 0.0008 g/100in2-24 hrs.
The transdermal patch, e-cigarette, and diagnostics markets are the first application opportunities company expects for this technology, which is also called an excellent candidate for single-dose delivery systems and cosmetic applications because of its high surface-to-volume ratio and unique barrier properties. Company also says the film is well suited for the emerging flexible packaging for wine and spirits segment because of its outstanding organoleptic characteristics.
